GE IC693CMM311J IC693CMM311N Communications Coprocessor Module

Product Description

The GE IC693CMM311J is a high-performance communications coprocessor module designed for GE Fanuc Series 90-30 PLC systems. It enhances serial connectivity, enabling reliable data exchange between PLCs and external devices such as HMIs, SCADA systems, and additional controllers. Moreover, its robust design ensures stable operation in demanding industrial environments.

This module supports multiple protocols including SNP, SNP-X, and Modbus RTU/ASCII, allowing flexible integration across varied industrial networks. Its dual serial ports provide simultaneous communication, while the single-slot, baseplate-mounted design ensures easy installation in any slot except the CPU slot. Therefore, it maximizes system expansion without occupying critical CPU space.

The IC693CMM311J offers precise control over serial communications and supports up to four CMM modules per system. In addition, LED indicators provide clear status monitoring for each port and overall module health. Its compatibility with modular Series 90-30 CPUs (311, 313, 323) ensures seamless integration and reliable performance in complex automation applications.
